Shellcode Injection via CreateThreadpoolWait Process Manipulating

Shellcode injection is a technique used by malware to execute arbitrary code within the context of a targeted process. One method of achieving this is through the use of the CreateThreadpoolWait function, which is a part of the Windows thread pool API.

In the context of shellcode injection, CreateThreadpoolWait is used to create a wait object that is associated with …

NOP Sled Anti-Disassembly

In computer security, a NOP slide is a sequence of NOP (no-operation) instructions that is inserted at the beginning of a code section. When a program branches to the start of this code section, it will "slide" through the NOP instructions until it reaches the desired, final destination. This technique is commonly used in software exploits to direct program execution …

Shikata Ga Nai (SGN) Data Obfuscation

Shikata Ga Nai (SGN) is a data obfuscation technique that employs a polymorphic binary encoding scheme. It was initially developed by Ege Balci and gained popularity through its implementation in Metasploit Framework's msfvenom. SGN takes a binary input and generates a self-decoding obfuscated shellcode. The algorithm utilizes a XOR feedback loop for encoding and prefixes a decoding routine to the …

Propagate Process Manipulating

This technique involves modifying the internal properties of a window in order to intercept and modify or monitor the behavior of the window when it receives messages. To do this, an application creates a buffer containing shellcode and injects it into the target process.

Then, it modifies the internal structure used by the specific properties, such as UxSubclassInfo and CC32SubclassInfo, …

Atom Bombing Process Manipulating

Atom Bombing is a technique that utilizes Windows Atom Tables, which provide a global storage mechanism for strings, to inject malicious code into a target process.

The technique involves storing a shellcode in an Atom Table, then using the NtQueueApcThread function to force the targeted process to access the specific Atom, causing the injection to occur. To bypass Data Execution …

NLS Code Injection Through Registry Process Manipulating

Dll injection through registry modification of NLS code page ID is a technique used by malware to inject a malicious DLL into a process by modifying the NLS code page ID in the registry.

There are two ways to accomplish this technique: 1. Calling the SetThreadLocale function and setting up an export function named NlsDllCodePageTranslation, where the main payload …

Return Address Spoofing Antivirus/EDR Evasion

Return Address Spoofing is a technique used in x64 architecture to bypass the limitations of the x64 fastcall mechanism. The traditional method of spoofing return addresses in x86 (e.g. using a ret in a game module as a trampoline) is not feasible in x64 due to caller cleanup and red zone.

To overcome this, the code creates a temporary storage …

Reflective DLL injection Process Manipulating

Reflective DLL loading refers to loading a DLL from memory rather than from disk. Windows doesn’t have a LoadLibrary function that supports this, so to get the functionality you have to write your own, omitting some of the things Windows normally does, such as registering the DLL as a loaded module in the process, potentially bypassing DLL load monitoring.

The …
